i have a 2003 trd double cab tacoma with the 3.4 and 255/85s on it and live in the high country of colorado and i cant drive up any hill with out losing speed unless im revved up to 4000 rpms. what can i do for more power or should i regear? i rather get the power becdause its easier but im up for ideas

short of adding a supercharger you won't make anymore HP. CAI, exhaust, ect, pretty much useless in gaining any real measureable power. Regearing is your best bet. A supercharger is way more costly less reliable for DD.

Bilstein 5100's and OME 882's in the front
AAL and Bilstein 5125's in the rear
Converted to 4x4, with 97 front diff with manual hubs
4.56 Yukons front and rear
Custom front bumper, sliders and under-belly skid by MOBS Fab in Concord,NC with built in hella's and 8000lb smitty

after doing 33's on my 3.4, I did new yukons, bearings and everything... that has been one of the best upgrades I have done... I was getting 14mpg around town and now I get 17mpg (and I like to let it open a good bit). It performs just like a stock truck, maybe a lil better... it's really quick on the take off.

i live at 9600 feet and do a fair amount of highway driving to moab, home to michigan, and to other ski areas but i also do a lot of wheeling so its a tough call, alove what gear ratio did you use? would deckplate, headers, a good muffler like super 44 and a tuner help?

4.56's put my truck back to stock mpg... i'm getting 17-18 mpg around town and i have gotten up to 21 hwy mpg (keeping it between 60-65 mph) plus i love having the get up and go...

I think..... if you're looking for more power you're in the wrong truck. V6's defiantely have a good amount of powers especially over the 4 cyl. But you're not going to get alot of power without supercharger/turbo. I feel like if you want more power you need to get into a different truck. These tacomas with the v6 have plenty of power, towing and hauling and pulling hills i feel is to much to ask for out of it. Don't get me wrong i love my truck (also have v6) but if i needed something other than being a DD and for 4 wheeling it would not be my first pic.
That said there are many things you can do to your truck to help it, but theres only so much you can get out of that motor

Yeah welcome to Colorado, right? When's the last time you tuned up? Don't know how long you've been in the high country, but the thin air simply sucks power from all vehicles, and the automatic doesn't help. Mostly because I don't have a desire to burn through a gallon of gas ever 5 miles by flooring it, I content myself just to drive 50mph over the high passes.

But 4000rpm really isn't that high at all .. I mean the truck can easily handle that kind of engine load for extended periods of time. Will a supercharger help? Maybe. But you still have to contend with the lack of oxygen up there.
